12. Which scaling approach adds more resources to existing servers, such as increasing CPU or RAM?

Horizontal scaling

Vertical scaling

Diagonal scaling

Distributed scaling

13. In a High Availability & Scaling (Cloud+) architecture, what triggers auto-scaling policies?

Fixed time intervals

Metrics like CPU usage, memory, or request count

Manual administrator decisions

Random system events

14. Which statement about stateless application design is true for horizontal scaling?

It is not required for horizontal scaling

It allows requests to be routed to any server without session loss

It only applies to database servers

It increases complexity for load balancers

15. Vertical scaling on a single instance can lead to what type of failure scenario?

Cascading network failures

Single point of failure

Load balancer timeout

Database replication lag

16. When implementing High Availability & Scaling (Cloud+), horizontal scaling across multiple availability zones provides which benefit?

Lower application latency

Disaster recovery and regional redundancy

Reduced software licensing costs

Simplified database management

17. Auto-scaling groups in cloud platforms typically implement which scaling type?

Vertical scaling only

Horizontal scaling

Static allocation

Manual resource provisioning

18. Which scenario best suits vertical scaling?

Handling sudden spikes in traffic

Increasing capacity of a single application with occasional moderate growth

Ensuring 99.99% uptime across multiple regions

Supporting millions of concurrent users

19. In cloud environments, horizontal scaling typically requires which component to distribute traffic?

Redundant power supplies

Load balancer

Backup database

Virtual private network

20. What is a primary limitation of vertical scaling?

It requires purchasing additional hardware licenses

It has physical hardware limits and a single point of failure

It always increases network bandwidth costs

It prevents load balancing across servers

21. Horizontal scaling involves adding more servers to a system. What is a key advantage of this approach?

Eliminates the need for load balancers

Provides high availability and fault tolerance

Requires no application modification

Reduces latency between users and servers
